Abstract: Blasting squeezing silt technology plays an important role in the marine reclamation and tidal power station seawall project construction. The thickness of soft clay that needs to be dealt with is gradually deepening with the continuous advance of marine engineering progressing to offshore and underwater shoals. The suspended seawall structure appears when soft clay is more than 12 m deep. Therefore, it is of great importance and of application value to carry out the settlement calculation and analysis. Taking Huizhou port depot revetment project for example, traditional settlement calculation method, the settlement calculation method considering buoyancy and numerical simulation method were applied to carry out settlement calculation; their results are compared with the actual monitoring results. Furthermore, the applicabilities and rationalities of these three methods are analyzed. It is shown that, the results of traditional settlement calculation method are significantly larger than the actual ones, it may not be suitable for suspended seawall; while the settlement calculation method considering buoyancy and numerical simulation method are suitable for suspended seawall because the calculation result are closer to the actual situation.

Key words: hydraulic structure, squeezing thick silt by blasting, suspended seawall, buoyancy, settlement calculation
